Hi All,
When i send the traffic outside of GRE tunnel, The speed is in 3-4Mbps.
When i use the tunnel for traffic, the speed get reduced huge. It is
around 100-300Kbps. What are the factors affects the performance when we
use tunneling [ ex:GRE tunneling ]?
Thanks
Jeba

Hello. You may try get slow place. Get pc without CPU load (console mode
and etc).
Try compile gre support in kernel. Turn on OPROFILE support.
Install oprofile utils.
do
opcontrol --vmlinux=/usr/src/linux/vmlinux
opcontrol -s
#do connect and try do traffic.
opreport -l | vi -
# you see that functions in kernel use cpu...
opcontrol -h #to stop
Maybe its help for you. Thanks!
